To 1.77 whom' if 711/17/ concern:

Be it known that l, AUBREY Bowne, acitizen or' the ifnitetil States, residing at Sanford,

in the county or Grange and State oi Florida, have invented a new and useful Journal Roller-Bearing, oi' which the following is a speciiication` rlliis inventionrelates to journal-hearings ior railwayjcars, trucks, and other rollingstoclv, and has for its objecty to provide an antiiriction-bearing which is comparatively simple in construction, veil'ective in operation, and one in which friction and wear on the several parts are reduced to a ininiinuni.

si further object of the invent-ion is to provide sectional journal-box the ends oi which are extended to forni a closure for the iree end oi the journal, so as to eil'ectuallj' prevent the ingress or' dust, dirt, and other foreign matter to the bearing.

A. still further object or' the invention is to generally improve this class of devices, so as to increase their utility, durability, and eiiiciencv, as well as to reduce the cost or' manufacture.

ll'ith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts, hereinafter iullv described, and illustrated in the accoinpanving drawings.

in the accompanving drawings, forming a part oi" this speciiication, .Figure l is a transverse sectional view of a j ournal-bcaring constructed in accordance with niv inventit'in. F 2 is a longitudinal sectional view of the saine. Fig. 3 is a perspective view of one oi the lantiiiictioii:tolle1s detached, and Fig. -iis a similar view or' one or' the spacing-blocks.

Similar numerals of reference indicate corresponding parts in all of the figures oi' the drawings.

The improved device consists of a journalbox, preferably formed in two sections 5 and o, detachablv secured together in an v suitable manner` as bj' bol'ts or similar fastening devices T, and in which is mounted i'or rota tion the axle or journal '.l`he staftions :3 and l are formed with angular stop ilanges il and itl. and bearing against said l'tanges and interposed between Vthe interior walls ol the journal-box set-tions and the journal o age a pluralit ol' antii'ric tion-rollers ]}.tlisposed concentric with thc journalfas shown. 'l `hc amil'rictiona'ollcrs ll are spaced apart l olongatcd blot-lts `the opposite longitntnnal edges of which are concaved, as indicated at i3, to conform to the curvature of the rollers il. The outer end of the 'axleor journal S terminates in an annular flange li. and formed integral with 'the j ournal-box sections 5 and t3 are depending portions l5, which. forni a closure for the outer end of the journal, so as to eiiectually prevent the entrance or' dust, dirt, or other foreign material to the bearing. The flange 1li is seated in an annular recess 16,fornied in the sections comprising the journal-box, the opposite ends oi thc journal being curved or rounded atv 1T to form seats for the ant iiricti oir-rollers.

The extensions .l5 not only prevent the dirt, grit, and other foreign inatcrial from entering the bearing`- and ahrading or otherwise injuring the bearing-surfaces, but also serve 'to prevent the escape of oil Orothcr lubricant introduced into the chamber formed bv said section.

llvliile the device is principallv designed i'or use onj cars and other rolling-stock, it is obvious tiatthe same majv be used with equally good results on carriages, wagons, shai'ting, or wherever a bearing or' this character is found desirable. Y

Having thus described the invention, what is claimed is-s ln a jtunnal-bearing, a sectional journalbox provided with annularstop-i'langes one oi' which i'ornis an annular recess at the rorward end oi" the journal box, a journal mounted ior rotation in said box and provided with a terminal llange seated in said annular recess, antilriction rollers interposed between the journal and the adjacent interior walls oi the sectionsA` said sections being each toi-med with an integral c.\;tcn sion the adjacent edges of which meet at the center oi' thc journal and il'oriu a closure for the outer end oi' thc latter. spacing-blocks having their opposite longitudinal edges concaved l'or engagement with the rollers, and bolts passing through openings. l'ormcd in said sections l'or dctachahlv securing the same in position on the jotti;nal, j*

ln tcstimtm) that l claim t'iit'iregsiing as in v own l have hereto allixcd nl v signature in thc present-c ol two witnesses. Y
